Why is Eid Al Ghadir the best Eid?
You fast for about a month and celebrate Eid al Fitr as a sign of thanking Allah for performing one of Allah’s obligations. Then inshallah you go to Hajj and perform Amal for several days and thank Allah by celebrating Eid Al Adha.
But when it comes to Eid al Ghadir, there isn’t something you do before, and it just finishes. The love that you have for Imam Ali is with you for every second, with every heartbeat, and for your whole life. Celebrating this day is a sign of thanking Allah, Prophet Muhammad, and Imam Ali for the great blessing of completing your religion by being a follower and lover of Imam Ali.
